Android 4.1 Jelly Bean has arrived, in the form of a preview version of the OS on the Galaxy Nexuses given away to Google I/O attendees. As we've already mentioned in our coverage of Jelly Bean, there's lots of new improvements to the OS. These are mainly based around making Android more slick and responsive to touch input, and eliminating lag wherever it occurs. There are also new software treats in the form of expanded notification functionality. Google Search has been overhauled, and Google Now presents relevant information based on your location, calendar and other stored data. Android Beam has been expanded too, with photo and video transfer capabilities
